Description
Square tube insert 140×140 mm, white

The white Square tube insert 140×140 mm provides a neat finish for open ends of hollow profiles. It is made of polyethylene and has an external flange and internal ribs that allow it to be fitted into the end of the profile.
Internal inserts of this type are used in hollow-profile structures where the open end needs protection against dirt and damage to the edges. The flange covers the edge of the profile, while the ribs fit inside and hold the insert in place.
Benefits and applications
- Neat white finish for the end of a square profile
- Protects the inside of the profile against dirt
- External flange covers the edge of the profile
- Internal ribs hold the insert in the profile
- Made of polyethylene

Polyethylene is a plastic commonly used to manufacture profile inserts. For installation companies, this is a simple finishing component that completes the assembly of hollow-profile structures and closes their ends once work is finished.
When selecting an insert, it is important to match it to the nominal profile size and wall thickness. Key dimensions, including the external and internal section heights and the core and rib dimensions, are listed in the specification tables below.
